What is a Patch Panel?

A patch panel is a piece of hardware with multiple ports that helps organize a group of cables. Each of these ports contains a wire that goes to a different location.  Patch panels can be quite small, with just a few ports, or very large, with many hundreds of ports. They can also be set up for fiber optic cables, cat5 cables, RJ45 cables, and many others.

What is a Patch Panel Used for?

Patch panels connect various IT devices together. They are in many different environments including communications closets, telephone company central offices, and data centers. Understanding the role they play can help to determine if your facility requires a patch panel, and if so, how to set it up.

Each port in a patch panel goes to a different device somewhere in the facility. Each panel bundles all the connections together in order to connect to another network. This is often how a LAN connects to a WAN, or to the Internet. Patch panels are also commonly used in facilities with a lot of telephone lines, in which one mainline is used for all phones.

Advantages of Patch Panels

Patch panels are an important piece of equipment in the data center. Using a patch panel comes with many advantages that make it well worth the investment. Some of the most significant benefits of using patch panels include:

Scalability – After installing a patch panel, you can easily add new devices without having to run new cables end-to-end.

Reduces Cable Clutter – Patch panels are typically located closer to the actual equipment. This makes it possible to use a shorter patch cable. From the panel, a fiber optic or other high capacity connection runs to the next network or the internet.

Inexpensive – Patch panels aren’t considered “smart” devices in that they don’t perform any function other than facilitating the passing of data. This means they are very inexpensive.

Lowering Cable Cost – Having a patch panel allows you to use shorter cables, which cost less than longer ones. Typically, you can also use inexpensive cat-5 cables to get to the patch panel rather than costly fiber optics.

Easier Maintenance – If you ever need to run a test cable, test a port, or perform any other common maintenance tasks, it can be done more quickly and is much easier than if each device had a cable run to its final destination.

Patch panels are one of the oldest types of technical equipment still popular today. They are quite simple in their design and function, but still, help to improve the organization and function of a data center or almost any other environment with lots of equipment.

Patch Panel Cable Management System

With dozens, or even hundreds, of cables coming into and out of a patch panel, it can be easy for things to become quite tangled and messy. Unorganized cables can make troubleshooting much more difficult, and can even lead to outages if someone unplugs the wrong cable. This is why it is critical to keep organization in mind from the first cable you plug in. There are many things that a person can do to help keep a patch panel organized, including:

Labeling Cables – All cables should be properly labeled at both ends, and in many cases, along the middle as well. Having labels on the cables will make it easy for technicians to confirm they are working on the right lines.

Patch Cable Organizers – Patch cable organizers allow you to run lines neatly and evenly to each port so you can see exactly where things are coming from and going to.

Color-Coded Cables – Using color-coded cables will allow you to quickly identify what type of cable is in each place.

Zip Ties – Using zip ties to bundle cables that are going to the same server rack or other location will help keep things looking neat and organized.

The most important thing when it comes to patch cable management is having a good plan right from the beginning. It is much easier to spend a little extra time coming up with a good way to run your cables than it is to try to untangle hundreds of wires down the road.

Optical fiber patch cords are widely used in data centers. In recent years, the demand for bandwidth in data center optical fiber transmission systems has shown a trend of high growth. Therefore, the use of a new generation of optical fibers and optical modules can continue to explore the potential of optical fiber network bandwidth growth. Because multi-mode fiber jumpers have great advantages in cost, they have an absolute advantage in data center applications.

Driven by the continuous application and promotion of network media in the cloud computing environment, multi-mode fiber optic patch cords are also constantly developing. From OM1 to OM2, and from OM3 to OM4, the VCSEL laser optimization technology used, and bandwidth requirements are constantly increasing. The introduction of the new category OM4 multi-mode patch cord fiber standard EIA/TIA492AAAD provides a better transmission method for the wide application of multi-mode fiber in the future. This article will provide an ideal communication solution for your data center, server, network switch, telecommunication switching center and many other embedded application systems that require high-speed data transmission.

In 40G/100G data transmission applications, the transmission port connection equipment, such as QSFP optical module, will be directly connected through MTP/MPO connectors regardless of the number of optical fiber connections used by the optical fiber channel, and regardless of the type of optical fiber connection. Because the 40G/100G data transmission application device and the channel connection between the device need to form a special mode, so that the channel of the transmitting end and the receiving end of the device correspond to each other, which requires the MTP/MPO connector to complete the connection.

MPO / MTP fiber optic patch cords can provide various applications for all networks and devices that require 100G modules. They adopt the MT series casing design of the high-density multi-mode fiber optic connector system industry, and the MPO/MTP fiber jumpers use UPC and APC polished end faces, and support both multi-mode and single-mode applications. With VCSEL laser and LED light source, 10G OM3/OM4 MPO/MTP fiber optic patch cords can provide 10Gbps data transmission rate in high bandwidth applications. They are 5 times faster than standard 50um fiber optic patch cords.

At the same time, multimode MPO / MTP fiber optic patch cords are also a more economical choice for most of the most common fiber optic communication systems. Single-mode MPO/MTP fiber jumpers are mainly used in long-distance data transmission systems. MPO/MTP backbone jumpers are specially designed for data center applications. Generally, single-mode and multi-mode MPO/MTP fiber jumpers are designed as round cables with an outer diameter of 3mm or 4.5mm. The connectors at both ends of the cable are also called MPO/MTP connectors.

At present, MPO/MTP high-density push-pull optical fiber jumpers are mainly used in three aspects: high-density cabling data centers, fiber to the home, and connection applications with optical splitters, 40G/100G QSFP+, SFP+ and other optical modules. Today, there are already a series of high-density parallel optical interconnection products that can adapt to the optical fiber transmission of modern data centers, such as custom MPO/MTP fiber jumpers, multi-mode fiber loopbacks and QSFP+ high-speed cable assemblies.

The development of server virtualization and cloud computing, as well as the development trend of network integration, has brought about the development of faster and more efficient data center networks. At present, the 10G switch composed of 48 10G channels is mainly limited to use SFP+ modules to realize the connection. In order to meet higher bandwidth requirements, users can use high-density QSFP+ high-speed cables to complete the connection, and increase the data transmission rate of each channel and increase the port density to meet the customer’s high bandwidth requirements.

The increasing demand for data transmission is driving the development of the entire optical communications market. Active optical cable AOC is a necessity for data transmission and can meet the needs of high-density and high-bandwidth applications. It has many advantages such as high transmission rate, long transmission distance, low energy consumption, and convenient use. It can help communication equipment enjoy the huge advantages of optical transmission. It is an ideal transmission cable for data centers, consumer electronics and other fields.

fiber-mart.com has been deeply involved in the field of multi-mode VCSEL optical modules and active optical cable AOC for many years. Among them, the data center AOC multi-mode product line has transitioned from the first generation of 10G/40G SR AOC to the mainstream application of 25G/100g SR AOC in the current market. Based on the purpose of market segmentation, Gigalight has defined and developed a series of differentiated 100G AOC products. Including standard SR4 AOC version, overclocking low-cost AOC lite version, eSR4 AOC version supporting 25GE zero error, eSR4+ AOC supporting dual rate, etc., which can provide customers with the best commercial choice.

The quasi-100G QSFP28 AOC SR4 standard version 100G QSFP28 AOC integrates four data channels in each direction with a bandwidth of 104 Gbps, which is used for short-distance multi-channel data communication and interconnection applications. Each channel uses OM4 to transmit a distance of 100 meters. The module uses a multimode optical fiber system with a nominal wavelength of 850nm. The electrical interface uses 38 contact edge type connectors, and the optical interface uses 12 optical fiber MTP (MPO) connectors. VCSEL laser is used to provide reliable long life, high performance and consistent service. At the same time, it can optionally support an industrial temperature range.

Overclocking low-cost AOC lite data center emphasizes low cost. Overclocking design is a technology developed in the past two years due to low-cost competition of 5G optical modules. The purpose is to design and match 10G optical components to work at 25G, thereby reducing the overall machine cost. Overclocking technology must meet the following preset conditions:

* Industry Agreement Standard

* General reliability standards

* Service life of the equipment

Active Optical Cable AOC’s transmission distance is relatively short, and the working environment is relatively good, which just provides a stage for AOC overclocking applications. Otherwise, 100G optical modules and 100G Active Optical Cable AOC are no different under cost measurement. Overclocking design can show the difference and application advantages of 100G AOC Active Optical Cable. However, under the above conditions, the overclocked optical module will be slightly inferior to the non-overclocked version (standard version) in function.
